Hi; this fails to build on various CI configs, eg:
https://gitlab.com/qemu-project/qemu/-/jobs/2137393314
https://gitlab.com/qemu-project/qemu/-/jobs/2137393335

../hw/openrisc/openrisc_sim.c:40:10: fatal error: libfdt.h: No such
file or directory
40 | #include <libfdt.h>
| ^~~~~~~~~~


This happens because meson doesn't put the include path for libfdt
on the include path for every .c file -- you have to do something
special in the meson.build file for the files that include it.
Paolo can tell you what that is, I expect.

Paolo: are we going to be able to stop doing this at some point
and get meson to just DTRT and put includes on the path for
every C file ?

thanks
